Q

Lumbar plexus

Study These Flashcards
A

-L1-L5: innervates anterior and medial muscles of the thigh, medial leg, and foot
-L2-L4: posterior branches form the femoral nerve, anterior branches form the obturator nerve

23
Q

Sacral plexus

Study These Flashcards
A
  • Primarily L5-S2: innervates buttocks, posterior femur muscles, and the entire lower leg
24
Q

Tibial nerve

Study These Flashcards
A
  • continues to descend in the posterior compartment of leg and foot
  • gastroc, soleus, Tom, dick and harry
25
Common peroneal nerve
- travels down the lateral and anterior compartment of the leg and foot - fibularis longus and brevis
26
L4-S3 (sciatic nerve)
- supply to biceps long head, semis, hamstrings
27
Constant LBP differential by pain pattern
-chemical pain, inflammation
28
Intermittent (70-80%) postural/mechanical dysfunction
Increased with sitting - Disk, SI joint sprain/inflammation Reduction with sitting - spondy, facet syndrome, stenosis Increased with standing - ligamentous/muscular instability Increased while side lyinh - same side> facet or disk -opposite side> disk Bowel/ bladder incontinence - disk extrusion/ sequestration - stenosis -cauda equina syndrome
29
Skin markings
Neurofibromatosis (cafe au lait) -genetic disorder causing tumors on nerve tissue - typically benign but sometimes malignant - type 1 in children Spina bifida (faun's beard)
30
Mechanical Low back pain
- muscle strain (erector spinae, semispinalis, multifidus) - spondylosis, spondylolysis, spondylolisthesis - spinal stenosis - osteoarthritis
31
Discogenic low back pain
- pain can be evident in MRI -annular tears - herniated nucleus pulposus (HNP) - types: protrusion, prolapse, extrusion, sequestration
32
Spinal stenosis
- common in 50-60 yrs old s/s: - pain during walking - weakness distal to insulting area - radiating pain, N/T
33
Intervertebral disk syndrome "degenerative disk disease" (DDD) etiologies
1. Poor posture chronically - loss of water content with age, decreased protein, and altering of chemical structure 2. Faulty mechanics - excessive flexion & rotation 3. Trauma - violent twist w/flexion
34
Intervertebral disk syndrome pathoetiology
- degeneration of annulus fibrosis - nucleus pulposes herniation- extrusion through the annulus fibrosus - nerve impingement (root or cord)
35
Intervertebral disk syndrome s/s
Radiculopathy - any disorder of spinal nerve roots Sciatica - any pain, N/T, affecting the distribution of the sciatic nerve
36
Sciatica
- affects 40% of population in their lifetime - multiple causes of sciatica: herniated disc, stenosis, piriformis syndrome, diabetes - could include dull, achy, sharp, radiating, tingling pain (increased with flexion/tension)
37
Stages of disc herniation
1. disc degeneration 2. prolapse 3. extrusion 4. sequestration
38
Disc degeneration
chemical changes associated with aging causes discs to weaken, without herniation
39
Prolapse
disc position changes with some slight impingement into the spinal canal. (bulge or protrusion)
40
Extrusion
the nucleus pulposus breaks through the annulus fibrosus but remains within the disc
41
Sequestration
the nucleus pulposus breaks through the annulus fibrosus and lies outside the disc in the spinal canal
42
Special tests for DDD
s/s: - regional pain/spasm - radiating pain - decreased patellar & achilles reflexes - tests: SLR, bowstring, valsalva, milgram's, brudzinskis, slump sit
43
Facet syndrome etiology
acute: forced extension (hyper) w/rotation Chronic: repetitive extension, hyperlordosis
44
Facet syndrome pathology
articular lesion, inflammation, osteophytes
45
Facet syndrome s/s
pain w/extension & rotation special test: + quadrant test
46
Spondylolysis etiology
congenital anomaly (pars defect) or repetitive extension causing degeneration & Fx
47
Spondylolysis pathology
degenerative fracture @ pars interarticularis
48
Spondylolysis s/s
regional, localized LBP that restricts extension special test: Single leg stance (stork stand)
49
Spondylolisthesis etiology
chronic LBP extension strain, postural anomaly, rarely direct blow
50
Spondylolisthesis pathology
bilateral fracture, subluxation, luxation, anterior displacement (L5 on S1, L4 on L5)
51
Spondylolisthesis s/s
- lower cross syndrome - step off deformity - decapitated scotty dog on Xray
52
Vertebral fx/ luxation etiology
axial load, hyperflexion/rotation, blunt trauma
53
Vertebral fx/luxation s/s
- cervical, chest, extremity pain - anesthesia, paresthesia in trunk/limbs - weakness - loss of bladder control
54
Scoliosis
-can be structural or functional - structural is rigid and fixed - usually diagnosed @ 10-15 yr old right after growth spurt -special test: adams forward bend test - brace as treatment
